To all whom 'may concern i Be it known that I, Joiiiv Aiii'rirnzV Kern, a subject of the King of Great Britain, residiiig'at Sault Ste.gMaiie, Province of Ontario, in the Dominion of .Caiiada, have in' vented a new and useful Mining-Drill; and I do hereby declare the following to a full,elear,-and exact description of theinveiition, such as -will enable others skilled in the art to which it appertains to make and use the same. f

' The presentinvention relates to a mining drill, and has for its object to provide a device of this character which embodies novel features of construction whereby a recipro-r eating drill of; either a large or a small size can be effectively operated by a single man. Further objects of the invention are to provide a mining drill which is portable and can be easily carried. from place to place, which provides a manually operated' mechanical means for reciprocating and turn ing the'drill bit iii the proper manner, and which can be easily mounted in operative position. y

.lVith these and other objects in view, the invention consistsin certain novel combinations aiid arrangements of the parts-as will more fully appear as the vdescription proceedsj the n'ovelfeatures thereof being point- For a full understanding of the invention,

.reference is to be had to the following descript-ion and accompanying drawing, in whichz- 'Figure 1 is a' vertical` sectional view'v through a mining` drillconstructed in ac ycordance with :the invention.. E ig. 2 isa side elevation thereof.` Fig. 3 is a detail view of the hammer in Vallthe views of the drawings by the same vreference eharacters.g

vided vn :fithteeth Q which are adapted tol bite into the surface o f the rock or other forma'- tioii'to1ivliich the device is applied and hold the drill firmly in position. A Vsleeve 3, eX- tends intothe basefrom they top thereof and is rigidly connected to the base, said sleeve being open' at both ends and receiving the lowerk end of a tubular guide 4 which is adjustable therein and projects up'-l wardly above thebase. This tubular guide L L is both removable and adjustable, and

loosely receives a reciprocating stock 5 which is provided at its lower end with a conventional drill bit 6. Iny the preseiitinstance the tubular guide et isshown as threaded in the sleeve 3,.;1 jam ynut 7 being providedy to hold tween the upper ends of the ystandards `9.and

has a pulley or drum 1 '1 rigidlyfitted upon the middle portion thereof. The ends of the shaft' are rigidly vconnected to the bifurcated end of .an operating lever 12which provides a means. for rotating the'shaft to wind a cable'lon the drum 11, and/alsov for turning,. the s'teck stepbystep abolita vertical;aXisto'shiftthefposition of the drill bit 6 inthe necessary manner, The'cable 13 is connected atV its lower end to an eye 14 .whiehwprojects from the'top lof a weight v15 andhas ya .swivel connection therewith, said weiglitbeintg"4 adaptedto be lifted by the windimgof ie cable 13 on the Vdrumll, and

to dropfwitha hammer-like.action on the upper end ofl thestock when released.

- Ak series vof wires 16 arepe'ndent from the periphery ofy the weight 15 andpass loosely through openings-1f?. in a Ydisk 18 which is `rigidly applied. to the,` stock 5 ata point .spaced from tlie iipper,.eiid thereof, and Y whichisv loose` within the tubular@ guide member 4. Theuppenends ofthe wires 16` are anchored in'a ringk '19 which is let into the edge .portion yof the weight at the botastheyscrews 20.' The lower endsof the wires arefeach provided 4-withfa weight'f21 tom thereof, beingreinova'bly heldin posi`n 5 k tion by suitable vfasten-ing riienibers` such which serves as a stop to engage thedisk 18 when the hammer has reached the upper limit of its movement, and also to hold the wire taut on'the downward movementof the hammer so that the wire will slidelfreely through the opening 17 of the disk instead.kr

ofV bending outwardly into the path of the hammer.

In `the operation of the' vminiiigdrill vtheY operating lever 12 is manipulated to rotate the drumy 11 and wind fthe cable 18l thereon,

thereby raising thek hammer 15 until the;

weights 21 at the lower ends of the wires16 engage the disk 1S. The operating lever is then Peating` this Operation successiveblows are l delivered upon the stock in the necessary manner to drive the 'drill bit into the roch or other Vxforiiiation being worked upon.' At

short intervals of time the stock and Vdrill bit are rota-ted step by step about a vertical axis *j terior ofthe sleeve 3.

by swinging theoperating lever 12 laterally. thereby shifting the position of the cutting edge ofthe drill bit at proper'intervals of time. y,As the hole which is drilled becomes deeper, drillv rod sections 22 may be successively added, so 'that a drilling string of the necessary length for operating at'any ordinary depth can be provided. It will be obvious that by removing the tubular guide 4; the stock 5 kand drilling string can'be lifted from 'the' opening, thereby enabling the drill bit to be sharpened or replaced, or an additional section `22 to be added to the drilling s tring.` For the purpose ofenablingwater vto be supplied to theidrill opening, tle base 1l is provided ywith a`w'ater pipe V211 whichf'is inclined downwardlyfrom .one of the sides" thereof and opens through the inf Water which` is poured into the pipe 2t'will be directedinto theorice so that it will descend tothe bottom vofthe hole and supply the necessary moisture for the properand effective operation L,of the .drill ybit. The weights 21 at'the lowerends of the'wires 16 are adjustably applied to;thewires so thatrthey'y can be positioned to regulate kthe stroke of the hammer 15. 'For this purpose theweights may be slidable on the wires andprovided with tapered and bifurcated ends .21a which are ythreaded* to receive clanfiping nuts 25. fVhen these nuts 25 are tightened the jaws pro Vvided bythe bifurcated end ofthe weight Y Yarelcausedto securely I'grip the wire to lhold he Weightn an adjusted position.; It will thus be obvious that by `properly position# ling the weights .the device .can 'be adjusted for along or a short hammer stroke, depending uponthe characterof the formation be ing ,op'eratedrupoin as Vwellas upon the size and eharacterof drill bit beinglused.r. Having thus described theinvention, what I claim as new and desire to secure by Letyters Patent, is
